This invention is directed to provision of high-performance inertial sensor that can sustain SNR even in an environment where vibration disturbance exists. Instead, an automatic frequency control is used to keep a continuous wave transmission tuned to the resonant frequency of a resonant microwave patch antenna. The internal line includes input terminal, connection electrode and a rod resistor. A query type for a query operator in the received query is identified. A spring encircling the arm rod is connected on a first end to the sliding plate foundation and on a second end to a stop coupled to the distal end of the arm rod.
